Is there a Fantastico like installer in the DirectAdmin interface, cause if there is, I can't find it

Unfortunately, no. What are you trying to install, a quick Google search will help you along the way.

you can still do that, you just have to upload it yourself. Search google and you'll find the official pages of those projects, there you'll also find extra info, the software and most likely a tutorial on how to install them.
